Subject [jira] [Commented] (CASSANDRA-3554) Hints are not replayed unless node was marked down
Date Mon, 05 Dec 2011 17:04:40 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-3554?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13162874#comment-13162874
] 

Jonathan Ellis commented on CASSANDRA-3554:
-------------------------------------------

The problem with a pull model is that the node doing the pulling usually won't know "I was
down, therefore I should ask for hints."  (The exception is on restart, but hints due to overload
conditions or GC pauses are much more common.)

> If B drops a write from A because it is overwhelmed (but not dead), A will hint the write.
 But it will never get notified that B is back up (since it was never down), so it will never
attempt hint delivery.
